An information-processing or knowledge-communication system designed for educational purposes. One of the earliest taxonomies of such systems(Hartley and Sleeman 1973) distinguishes four classes : conventional CAI or prestructured systems(called AFO, ad hoc frame-oriented systems by Carbonell in 1970) ;generative systems programmed to generate simple tasks by piecing problems(intermediate between conventional and intelligent systems) ;adaptive systems(such as the INTEGRATION tutor, whose domain expertise can be modified or adapted to student needs and characteristics) ;and self-improving(evolutive, truly intelligent) systems able to improve their teaching strategies and refine their knowledge by evaluating their own performance(e. g. the QUADRATIC tutor) [According to source WAITS 1987]  4, record 3, English, - computer%2Dbased%20teaching%20system

If the student’s approach leads to a better solution than the trace stored in the expert’s archive, the system adopts the student’s solution as its standard: hence the label of self-improving sometimes given this tutor.  4, record 4, English, - self%2Dimproving%20tutoring%20system
